RESUMO:

Monitoring programs in the Amazon are essential to contribute to the identification of illegal deforestation and thus guide decision making by Organs responsible agencies. Thus, the objective of this work was to identify the expansion of soybean farming in disagreement with the Soy Moratorium (MS) in the Amazon biome of Mato Grosso over the years 2008 to 2019. Data from PRODES (Deforestation Calculation Program in the Amazon), ImazonGeo (Geoinformation Program on the Amazon) and the Perpendicular Vegetation Crop Enhancement Index (PCEI) were used. The Kernel Density Estimator (DK) was applied to verify the areas (polygons) of major occurrences converted from forest-soybean and the Pettitt and Mann-Kendall test were applied to identify trends throughout the time series. The results showed that during the period from August 2008 to October 2019, 1,387,288 hectares were deforested according to PRODES data and 108,411 hectares were replaced by soybeans. ImazonGeo data showed 729,204 hectares deforested and 46,182 hectares converted to soybean areas. Based on the deforestation polygons of the two PRODES and ImazonGeo databases, the DK estimator indicated that the regions with the highest occurrences at odds with the MS were in the South, Southeast and East. The municipalities with the largest areas at odds with MS were Feliz Natal with 11.,169 hectares and Tabaporã with 9,865 hectares according to PRODES data and Feliz Natal with 6,157 hectares and Nova Ubiratã with 4,786 hectares according to ImazonGeo. The results indicate that the PRODES system presented, in all cases, greater variability in the data and means statistically superior to the ImazonGeo.
